Same problem here, started about 3 days ago, cursor flashing rapidly between microsoft cursor and 12sky2 cursor, gives me lag.
Yes im using intergrated graphics atm, but that shouldnt have to do with it since its an intel hd 4000 intergrated graphics (works fine for 99% of games ive played), also....my brothers pc is having the same issue with this game as well and he has a radeon 6570 hd.
All my drivers are up to date, and like i said this started happening about 3 days ago for me, and started yesterday for my brother (new hdd installed on his pc so fresh install of 12sky2, so maybe its a patch issue...idk).
I've tried manual repatching, removing aeria ignite, changing to windowed mode, changing resolutions, changing mouse settings, im using an old acer corded laser mouse and g15 keyboard, my brother is using a logitech g7 mouse. Game was working fine before, not sure why now.... Also..sometimes it will give me "error 002" and wont let me login at all.
